3/4
• Torque " bolts to 210 ft-lbs minimum.
10. Make sure that the 5th wheel coupler located in
the tow vehicle is mounted according to the proper
instructions of the 5th Wheel manufacturer. In addition,
make sure that it is in good working condition. A non- or
poor-working coupler will affect pin box performance,
resulting in an unsafe towing condition. Make sure the 5th
Wheel connection is never located behind the center of the
drive axle.
11. After all nuts and bolts have been tightened, attach
trailer to tow vehicle. Before applying the air nozzle fitting
at the top of the pin box, make sure the alignment pin is in
the hole on the bottom of the air spring.
12. With the tow vehicle at rest, inflate the air bag with
enough air to raise the pin box to the ride height mark
on the front of the shock absorber (Fig.3A). The starting
pressure should be around 80-90 psi, with the pressure

Operation

AN OVERINFLATED AIR BAG CAN BURST, RESULTING IN
DEATH, SERIOUS PERSONAL INJURY, SEVERE PRODUCT
AND/OR PROPERTY DAMAGE. DO NOT OVERINFLATE AIR
BAG. INFLATE AIR BAG TO RIDE HEIGHT LEVEL IDENTIFIED
ON THE SHOCK ABSORBER.
THE AIR BAG CAN LOSE AIR OVER TIME, RESULTING IN
REDUCED OR LOSS OF PRODUCT PERFORMANCE. REDUCED
OR LOSS OF PRODUCT PERFORMANCE CAN CAUSE
PRODUCT AND/OR PROPERTY DAMAGE. ALWAYS VERIFY
CORRECT LEVEL AGAINST THE SHOCK'S HEIGHT MARK AND
TRAILER BEFORE TRAVELING. ADJUST AIR PRESSURE AS
NECESSARY TO ACHIEVE CORRECT PIN BOX LEVEL.
AN UNSECURED AIR SPRING DURING INFLATION CAN CAUSE
PERSONAL INJURY. MAKE SURE AIR SPRING IS PROPERLY
SECURED TO THE PIN BOX BEFORE INFLATING. INSTALL AIR
CAP TO SAFELY COMPLETE AIR SPRING INFLATION.
